Abstract: The present invention relates to a ligand compound, an organic chromium compound, a catalyst system for ethylene oligomerization, a preparation method thereof, and an ethylene oligomerization method using the same. The catalyst system for ethylene oligomerization according to the present invention is used to prepare a low-density polyethylene in one reactor by using a small amount of comonomers such as alpha-olefin or by using only ethylene without comonomers, because it maintains high catalytic activity and high alpha-olefin selectivity even though supported on a support.

Abstract: The present invention relates to a photocatalyst toothbrush using an AOP (advanced oxidation process) which is configured such that a light source unit 113 such as UV lamps is attached to a photocatalyst reaction unit 114 coated with a photocatalyst such as TiO2, superoxide anion and OH radical are generated by a photocatalyst action, and the generated superoxide anion and OH radical are collected and are transferred together with external air to an oral cavity by using an air pump 115. In this way, organic substances, such as food, viruses, bacteria, plaque, tartar, etc., existing in the oral cavity are decomposed and removed so as to provide a clean oral-cavity state. Since the exemplary embodiment of the present invention is innovative in the generation and transfer configuration of anion and OH radical and has a simple configuration, the manufacturing is easy.

Abstract: Disclosed is a cooling apparatus of a color wheel for color separation in a single plate type projector and a projection system using the projector, which comprises an airflow generator, thereby cooling the color wheel and a rod lens of the single plate type projector. The cooling apparatus of the color wheel of the projector of the present invention prevents the color wheel and the rod lens from being thermally degraded by using the high-powered lamp. Further, an airflow generator such as the airfoil-shaped or plate-shaped blades is formed on a hub of the color wheel, thereby miniaturizing the system of the projector and reducing its production cost.
